When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise.
The coolant level should be up to
the base of the f iller neck. Addcoolant if it is low.
Pourthecoolantslowlyand
caref ully so you do not spill any.
Clean up any spill immediately; it
could damage components in the
engine compartment.
Put the radiator cap back on and
tighten it.
Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components.
Check the f luid level in the
windshield washer reservoir at least
monthly during normal use. If the f luid level
is low, a message will be shown on
the multi-information display.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them.

Do not use engine antif reeze or a
vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer f luid.

Check the f luid level with the engine
at normal operating temperature.Park the vehicle on level ground.
Shut of f the engine.
Within 60 to 90 seconds, remove
the dipstick (yellow loop) f rom the
transmission, and wipe it with a
clean cloth.
Insert the dipstick all the way into
the transmission securely. Remove the dipstick, and check
the f luid level. It should be
between the upper and lower
marks.
If the level is below the lower
mark, add f luid into the f iller hole
to bring it to the upper mark.
The transmission should be drained
and ref illed with new f luid when this
service is shown on a maintenance
message in the multi-inf ormation
display.Always use Honda ATF-Z1
(automatic transmission f luid). If
it’s not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can af f ect the shif t quality.
Have the transmission f lushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.
To thoroughly f lush the
transmission, the technician
should drain and ref ill it with
Honda ATF-Z1, then drive the
vehicle f or a short distance. Do
this three times. Then drain and
ref ill the transmission a f inal time.
Insert the dipstick all the way back
in the transmission.

Check the f luid level with the
transmission at normal operating
temperature and the vehicle sitting
on level ground. Remove the check
bolt, and look f or transmission f luid
coming out of the bolt hole. If a small
amount of f luid drips out of the bolt
hole, reinstall the check bolt.If no f luid comes out, remove the
f iller bolt. Slowly add Honda Manual
Transmission Fluid (MTF) until it
starts to run out of the check bolt
hole. Let the f luid run out until it
stops, then reinstall the check bolt
and the f iller bolt.
If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certif ication seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives, and continued use can
cause stiffer shifting. Replace as
soon as it is convenient.
The transmission should be drained
and ref illed with new f luid when this
service is shown on a maintenance
message in the multi-inf ormation
display.

Check the brake f luid level in the
reservoirs monthly af ter removing
the engine compartment rear cover
(see page ).The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If it is not, add
brake f luid to bring it up to that level.
Use the same fluid specified for the
brake system.
A low f luid level can indicate a leak
in the clutch system. Have this
system inspected as soon as possible.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage. Replace the brake f luid every 3 years,
independent of mileage.
Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement.
Using any non-Honda brake f luid can
cause corrosion and decrease the lif e
of the system. Have the brake
system f lushed and ref illed with
Honda Heavy Duty Brake Fluid
DOT 3 as soon as possible. 217

Pour the f luid slowly and caref ully so
you do not spill. Clean up any spill
immediately; it could damage
components in the engine
compartment.
Check the level on the side of the
reservoir when the engine is cold,
and the engine compartment right-
side cover is of f (see page ). The
f luid should be between the UPPER
LEVEL and LOWER LEVEL. If not,
add power steering f luid to the
UPPER LEVEL mark. Always use Honda Power Steering
Fluid. You may use another power
steering f luid as an emergency
replacement, but have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently, and have
the system inspected as soon as
possible.

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run. When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound or series of clicks, or
nothing at all.
Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the f uses. If the f uses
are OK, there is probably
something wrong with the
electrical circuit f or the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem (see
on page ).
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the vehicle
f rom a booster battery (see page ).
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
on page .
Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, the shif t
lever must be in Park or neutral.

In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to the START (III)
position, but the engine does not run.Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).
Are you using the proper starting
procedure? Ref er to on page . There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).

µOnce the vehicle is running,
disconnect the negative cable f rom
the grounding strap on your
vehicle, then from the booster
battery. Disconnect the positive
cable f rom your vehicle, then f rom
the booster battery.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until everything is
disconnected. Otherwise, you may
cause an electrical short. Start the vehicle. If the starter
motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact.
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of
the engine.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle. 7. 6.

Put the radiator cap back on
tightly. Run the engine, and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeon page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark
(see
on
page ).
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator. Start the engine, and set the
interior temperature to maximum.
Add coolant to the radiator up to
the base of the f iller neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and
ref illed with the proper mixture as
soon as you can.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(seeon page
).
Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.
This indicator should never
come on when the engine is
running. If it starts f lashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action. If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.
